Athletes from around the world recently competed at this year's FINA World Aquatics Championships. This year, the event was held in Gwangju, South Korea. It took place from July 12 to July 28.

In the wee hours of July 27th, several water polo competitors were at a nightclub. Some of them were celebrating their recent success in the women's medal rounds. But tragedy would strike.

A balcony collapsed

At roughly 2:30 in the morning local time, many people were dancing on a balcony in the club. Suddenly, the floor of the balcony gave out. People began landing on each other and some were struck by debris.

Two native South Koreans would perish from their injuries. Several other people were injured to varying degrees. Details have remained elusive to an extent, but some have emerged.

Members of both the women's and men's U.S. teams were there. USA Today reports that American Kaleigh Gilchrist required surgery from a leg injury sustained in the incident. Gilchrist was a member of the 2016 Olympic gold medal team. Another female team member and two members of the men's team were also injured.
